Chess, an ancient game.

But...

Did you know there's a little "easter egg" game of chess in facebook, not an app, but built in to messenger, both the messenger app and browser based. It's rather fun

@fbchess play



Each piece is represented by its first letter except the Knight which is N (as K is the King)

You move by sending a message with the piece and new co-ordinates so if you want to move a pawn to square e3 you do

Hope you enjoy it. I'm terrible at chess, but I'll give anyone a game if they want.
